Human Positioning System
Markerless Augmented Reality
Augmented Reality creates interactive composite views of the real world and and computer generated information. Augmented Reality alters real world environments with elements of sound, video, graphics or 3D objects. It is related to a more general concept called mediated reality, in which a view of reality is modified by a computer. As a result, the technology functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real world with a simulated one. The human positioning system, otherwise known as HPS, is an markerless augmented reality tool.
Marker-Based Augmented Reality relies on the device to identify artificial markers in the real world. The markers have to be in clear view of the device and it requires significant image processing tasks done by the computer. Other problems associated with marker tags is that they must be visible and easily recognized for the camera to recognize and interpret. Issues arise when real world objects obstruct the devices view of the marker.
Positional-Based Augmented Reality uses GPS coordinates and accelerometer data to superimpose images on top of the real world. The device does not need to process any of the visual data in the real world, it only requires location information. The flaws of Postional-Based Augmented Reality is that GPS data is not reliably accurate to a pin-point location and cannot be used indoors or where GPS strength is weak, without additional hardware.
Object Recognition is the use of computer vision to recognize real world objects directly. As a processor heavy task, it can identify features and is markerless. Currently object recognition is is frequently inaccurate and requires intensive processing which is not ideal for portable devices, such as cell phones and AR glasses.
The Human Positioning System is a patented technological method of initiating location specific augmented reality. It combines the aspects and benefits of the three major augmented reality triggers. By using photographs or digital depictions of a particular location, HPS lets the user process a reference image, by orienting their device to the real world. Once aligned, a digital scene is displayed to the user transposed and combined with the camera view of the current, real-world environment in that location. This works exceptionally well in crowded urban areas where it is likely that people or vehicle traffic might obstruct a scene. As well as anywhere that has a drastic visual change in seasons and weather. By utilizing the user-interaction between the augmented reality device and the real world, HPS has the user’s brain complete the processing of image-recognition. Allowing for quicker initialization for the augmented reality experience and accuracy wholly dependent on the user’s ability to recognize objects.
